Temperamental emotionality in preschoolers and parental mood disorders

A number of models developed in the adult psychopathology literature (i.e., L. A. Clark & D. Watson, 1991) have asserted that low levels of positive emotionality (PE) are predisposing factors or precursors for depression and represent a form of temperamental risk for depression. Further support for this claim would derive from evidence linking low PE to known indicators of risk for depression. The authors examined the association between temperamental emotionality in young children and parental mood disorders. One hundred unselected preschool-aged children completed a battery of emotion-eliciting tasks tapping aspects of PE, negative emotionality (NE), and behavioral inhibition (BI). Parental psychopathology was assessed with semistructured diagnostic interviews. Low PE in children was associated with maternal, but not paternal, mood disorder. The low PE-maternal depression link was relatively specific, as there were few associations between low PE and other forms of parental psychopathology or between NE and BI and parental mood disorders.
